Fabrics, furs and things made in w-hole 5 representsa long narrowshallow 'pan'offi" or in part thereof may be protectedfrom the ravages ofmoths or'other insectv life by sealing them up in a closed chamber'and' subjecting them to the a ction of the fumes or vap'o-rs'ofvolatile compoundscapable of destroying insect :life whether, in egg form or in a more developed state. The fumigant should be held in the fumigating chamber in such a Way that it may vaporize free-ly witlr out being spilled on the contents of the chamber in liquid form, and it should also be easy-to fill the container for the fumigant.

The object of the present invention is to produce a simple and 'novelrcontainer for any desired-quantity of fumigat-ing liquid, which will at the same time insure effective A further object of'the present invention isto provide a fumigating chamber with a simple and novel container for a fumigating liquid, so constructed and arranged that the liquid may be placed in the container from a point outside of the chamber and will be prevented from entering the chamber except in vapor form. I

The various features of novelty whereby my invention is characterized will hereinafter be pointed out with particularity in the claims; but, for a full understanding of my invention and of its objects and advantages, reference may be had to the following detailed description taken in connection with the accompanying draw ng, where1n:

a Figure 1 is a side view of the upper portion of a fumigating vault or chamber having one of my improved containers applied thereto; Fig. 2 is a vertical longitudinal section, on an enlarged scale, through one end of the container; and Fig. 8 is a trans-- verse section through the container. I

Referring to the drawing, 1 represents a suitable vault or chamber having atthe front a door 2 through which articles to be fumigated may be placedin the vault or chamber. Extending along the top. of the vault or chamber is a trough-like container A the top edges'of which preferably engagewith the top wall 3 of the vault; the container being closed at both ends as will-hereinafter beexplained. In the top wall of the vault is an inlet 4 through which liquid may bepoured into the container.

The details of the containerare shown in Figs. 2 and Referring to'these figures,

than the pane, Theside walls 8 and the end walls 9 extend upw'a i'dly, while the 7 3 bottom wall lies flat on the memberfi. The members 5, 6 and. 7 are glued together so 9 somewhat;"narrower *andsomewhat shorter; I

whose side and end walls 10- are'made of 70 j 7 layers of absorbent material extending along the marginal portions ofthe bottom panel. r

The-side and end walls 10 ha ve grooves cut into their bottom faces to receive the side'and end walls of the pan 7 thus uniting ,the'bottompanel and the side andend walls of the trough securely and at the same time preventing an excess of the liquid B in the.'trough from. flowing through the lower regions of the side and end walls'of'the trough,

out

As previously stated, this trough is. set into the fum gating vault or chamber against or close tothe top wall. lVhen fumigating liquid is poured into the trough, it passes i i through the sides 'of the latter by capillary action and evaporates from the external surfaces. Slnce the evaporation takes place along vertical surfaces spaced apart from each other, the fumes will drop down into" 7 the chamber as soon as they are formed, so
